PostgreSQL Project reports:
A modified, unauthenticated server can send an unterminated string during the establishment of Kerberos transport encryption. When a libpq client application has a Kerberos credential cache and doesn't explicitly disable option gssencmode, a server can cause libpq to over-read and report an error message containing uninitialized bytes from and following its receive buffer. If libpq's caller somehow makes that message accessible to the attacker, this achieves a disclosure of the over-read bytes. We have not confirmed or ruled out viability of attacks that arrange for a crash or for presence of notable, confidential information in disclosed bytes.
Grafana Labs reports:
On 2022-12-16 during an internal audit of Grafana, a member of the security team found a stored XSS vulnerability affecting the core plugin GeoMap.
The stored XSS vulnerability was possible due to SVG-files weren't properly sanitized and allowed arbitrary JavaScript to be executed in the context of the currently authorized user of the Grafana instance.
Grafana Labs reports:
A third-party penetration test of Grafana found a vulnerability in the snapshot functionality. The value of the originalUrl parameter is automatically generated. The purpose of the presented originalUrl parameter is to provide a user who views the snapshot with the possibility to click on the Local Snapshot button in the Grafana web UI and be presented with the dashboard that the snapshot captured. The value of the originalUrl parameter can be arbitrarily chosen by a malicious user that creates the snapshot. (Note: This can be done by editing the query thanks to a web proxy like Burp.)
We have assessed this vulnerability as having a CVSS score of 6.7 MEDIUM (CVSS:6.7/AV:N/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:L).
The OpenBSD project reports:

The OpenSSL project reports:
X.400 address type confusion in X.509 GeneralName (CVE-2023-0286) (High): There is a type confusion vulnerability relating to X.400 address processing inside an X.509 GeneralName. X.400 addresses were parsed as an ASN1_STRING but the public structure definition for GENERAL_NAME incorrectly specified the type of the x400Address field as ASN1_TYPE. This field is subsequently interpreted by the OpenSSL function GENERAL_NAME_cmp as an ASN1_TYPE rather than an ASN1_STRING.
Timing Oracle in RSA Decryption (CVE-2022-4304) (Moderate): A timing based side channel exists in the OpenSSL RSA Decryption implementation which could be sufficient to recover a plaintext across a network in a Bleichenbacher style attack. To achieve a successful decryption an attacker would have to be able to send a very large number of trial messages for decryption. The vulnerability affects all RSA padding modes: PKCS#1 v1.5, RSA-OEAP and RSASVE.
X.509 Name Constraints Read Buffer Overflow (CVE-2022-4203) (Moderate): A read buffer overrun can be triggered in X.509 certificate verification, specifically in name constraint checking. Note that this occurs after certificate chain signature verification and requires either a CA to have signed the malicious certificate or for the application to continue certificate verification despite failure to construct a path to a trusted issuer.
Use-after-free following BIO_new_NDEF (CVE-2023-0215) (Moderate): The public API function BIO_new_NDEF is a helper function used for streaming ASN.1 data via a BIO. It is primarily used internally to OpenSSL to support the SMIME, CMS and PKCS7 streaming capabilities, but may also be called directly by end user applications.
Double free after calling PEM_read_bio_ex (CVE-2022-4450) (Moderate): The function PEM_read_bio_ex() reads a PEM file from a BIO and parses and decodes the "name" (e.g. "CERTIFICATE"), any header data and the payload data. If the function succeeds then the "name_out", "header" and "data" arguments are populated with pointers to buffers containing the relevant decoded data. The caller is responsible for freeing those buffers. It is possible to construct a PEM file that results in 0 bytes of payload data. In this case PEM_read_bio_ex() will return a failure code but will populate the header argument with a pointer to a buffer that has already been freed. If the caller also frees this buffer then a double free will occur. This will most likely lead to a crash. This could be exploited by an attacker who has the ability to supply malicious PEM files for parsing to achieve a denial of service attack.
Invalid pointer dereference in d2i_PKCS7 functions (CVE-2023-0216) (Moderate): An invalid pointer dereference on read can be triggered when an application tries to load malformed PKCS7 data with the d2i_PKCS7(), d2i_PKCS7_bio() or d2i_PKCS7_fp() functions.
NULL dereference validating DSA public key (CVE-2023-0217) (Moderate): An invalid pointer dereference on read can be triggered when an application tries to check a malformed DSA public key by the EVP_PKEY_public_check() function. This will most likely lead to an application crash. This function can be called on public keys supplied from untrusted sources which could allow an attacker to cause a denial of service attack.
NULL dereference during PKCS7 data verification (CVE-2023-0401) (Moderate): A NULL pointer can be dereferenced when signatures are being verified on PKCS7 signed or signedAndEnveloped data. In case the hash algorithm used for the signature is known to the OpenSSL library but the implementation of the hash algorithm is not available the digest initialization will fail. There is a missing check for the return value from the initialization function which later leads to invalid usage of the digest API most likely leading to a crash.

Prometheus team reports:
Prometheus and its exporters can be secured by a web.yml file that specifies usernames and hashed passwords for basic authentication. Passwords are hashed with bcrypt, which means that even if you have access to the hash, it is very hard to find the original password back. Passwords are hashed with bcrypt, which means that even if you have access to the hash, it is very hard to find the original password back. However, a flaw in the way this mechanism was implemented in the exporter toolkit makes it possible with people who know the hashed password to authenticate against Prometheus. A request can be forged by an attacker to poison the internal cache used to cache the computation of hashes and make subsequent requests successful. This cache is used in both happy and unhappy scenarios in order to limit side channel attacks that could tell an attacker if a user is present in the file or not.

Tim Wojtulewicz of Corelight reports:
A missing field in the SMB FSControl script-land record could cause a heap buffer overflow when receiving packets containing those header types.
Receiving a series of packets that start with HTTP/1.0 and then switch to HTTP/0.9 could cause Zeek to spend a large amount of time processing the packets.
Receiving large numbers of FTP commands sequentially from the network with bad data in them could cause Zeek to spend a large amount of time processing the packets, and generate a large amount of events.

Plex Security Team reports:
We have recently been made aware of a security vulnerability in Plex Media Server versions prior to 1.25.0 that could allow a local Windows user to obtain administrator privileges without authorization. To be clear, this required the user to already have local, physical access to the computer (just with a different user account on Windows). There are no indications that this exploit could be used from a remote machine.
Plex Media Server versions 1.25.0.5282 and newer are not subject to this vulnerability, and feature additional hardening to prevent similar issues from occurring in the future. Users running older server versions are encouraged to update their Plex Media Server installations.

MITRE reports:
NLnet Labs Krill supports direct access to the RRDP repository content through its built-in web server at the "/rrdp" endpoint. Prior to 0.12.1 a direct query for any existing directory under "/rrdp/", rather than an RRDP file such as "/rrdp/notification.xml" as would be expected, causes Krill to crash. If the built-in "/rrdp" endpoint is exposed directly to the internet, then malicious remote parties can cause the publication server to crash. The repository content is not affected by this, but the availability of the server and repository can cause issues if this attack is persistent and is not mitigated. .
MITRE reports:
It seems #90 is not completely fixed in 7.8. (that is, even after CVE-2017-1000501 and CVE-2020-29600 are fixed). In AWStats through 7.8, cgi-bin/awstats.pl?config= accepts a partial absolute pathname (omitting the initial /etc), even though it was intended to only read a file in the /etc/awstats/awstats.conf format. NOTE: this issue exists because of an incomplete fix for CVE-2017-1000501 and CVE-2020-29600.

Peter Ammon reports:
fish is a command line shell. fish version 3.1.0 through version 3.3.1 is vulnerable to arbitrary code execution. git repositories can contain per-repository configuration that change the behavior of git, including running arbitrary commands. When using the default configuration of fish, changing to a directory automatically runs git commands in order to display information about the current repository in the prompt. If an attacker can convince a user to change their current directory into one controlled by the attacker, such as on a shared file system or extracted archive, fish will run arbitrary commands under the attacker's control. This problem has been fixed in fish 3.4.0. Note that running git in these directories, including using the git tab completion, remains a potential trigger for this issue. As a workaround, remove the fish_git_prompt function from the prompt.

The Tor Project reports:
TROVE-2022-002: The SafeSocks option for SOCKS4(a) is inverted leading to SOCKS4 going through
This is a report from hackerone:
We have classified this as medium considering that tor was not defending in-depth for dangerous SOCKS request and so any user relying on SafeSocks 1 to make sure they don't link DNS leak and their Tor traffic wasn't safe afterall for SOCKS4(a). Tor Browser doesn't use SafeSocks 1 and SOCKS4 so at least the likely vast majority of users are not affected.
lu4nx reports:
GNU Emacs through 28.2 allows attackers to execute commands via shell metacharacters in the name of a source-code file, because lib-src/etags.c uses the system C library function in its implementation of the ctags program. For example, a victim may use the "ctags *" command (suggested in the ctags documentation) in a situation where the current working directory has contents that depend on untrusted input.

Marcus Eriksson reports:
When running Apache Cassandra with the following configuration: enable_user_defined_functions: true enable_scripted_user_defined_functions: true enable_user_defined_functions_threads: false it is possible for an attacker to execute arbitrary code on the host. The attacker would need to have enough permissions to create user defined functions in the cluster to be able to exploit this.
